Ban Chiang is…

a village/mortuary site in northern northeast Thailand, in the province of Udon Thani.

Excavated by Chet Gorman of the University of Pennsylvania Museum and Pisit Charoenwongsa of the Thai Fine Arts Department in 1974-1975, this extraordinary site was among the first to establish the existence not only of a hitherto unknown prehistoric culture, but also of a separate bronze age in Southeast Asia.
